Abstract
Palladium catalyzed Suzuki-Miyaura cross-coupling of 6,8-dibromo-4-chloroquinoline-3-carbaldehyde with arylboronic and arylvinylboronic acid derivatives in the presence of potassium carbonate in aqueous dioxane afforded the corresponding 4,6,8-triarylquinoline-3-carbaldehydes, exclusively. These products were transformed into 4,6,8-triaryl-3-(4-fluorophenyl)amino)-N-(quinolin-3-yl)methylenes and their 4,6,8-triaryl-quinoline-3-methanol derivatives. The absorption and emission spectra were measured for the 4,6,8-triarylquinoline-3-carbaldehydes and their derivatives in selected solvents of different polarity.
摘要
钯催化 6,8-二溴-4-氯喹啉-3-甲醛与芳基硼酸和芳基乙烯基硼酸衍生物的 Suzuki-Miyaura 交叉偶联反应，在碳酸钾存在下于水-二氧六环中进行，可得到相应的 4,6,8-三芳基喹啉-3-甲酰基化合物，为唯一产物。这些产物被转化为 4,6,8-三芳基-3-(4-氟苯基)氨基-N-(喹啉-3-基)甲亚胺和它们的 4,6,8-三芳基喹啉-3-甲醇衍生物。在不同极性的选定溶剂中，对 4,6,8-三芳基喹啉-3-甲酰基化合物及其衍生物的吸收和发射光谱进行了测量。
